POLE-SOCKET.v

SPECIFICATION forming part of Letters Patent No. 572,778, dated December8, 1896.

Application iilecl April 30,1896. Serial No. 589,685. (No model.)

To all whom it may concern:

' Be it known that I, JOHN H. STEvENsoN, a citizen of the United States,residing at Ann Arbor, in the county of Washtenaw and State of Michigan,have invented certain new and useful Improvements in Pole Sockets, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The invention consists in the construction of a pole-socket formed froma single piece of metal in the shape of a segment of a circle slightlygreater than a half-circle, having securing-lugs integrally therewith inthe lower part of one edge, and, further, in theconstruction,arrangement, and combination of the various parts, as morefully hereinafter described and claimed.

In the drawings, Figure 1 is a plan showing the blank from which mysocket is formed. Fig. 2 is a perspective view of the socket detached.Fig. 3 is an end elevation showing it as secured in position. Fig. 4 isa longitudinal section showing the pole as in position in the socket.

In the manufacture of my polesocket I take a piece of sheet metal A andstrike it out in the shape shown in Fig. 1,' leaving upon one side theapertured lugs B at or near the middle thereof. These apertured lugs areturned up at'right angles to the body portion A, proj ecting beyond therear face of the body portion substantially the thickness of the metal,and the body portion is bent into the segment of a circle slightlygreater than a halfcircle, forming the arms C, extending up from eachside of the securing-lugs, the upper ends of which are bent outwardly toform the inclined entering lips D. When thus shaped, the device may besecured in position by nails or screws driven into the wood of a Windowor door casing through the apertures in the lugs B, as shown in Fig. 4,with the arms D eX- tending upwardly, the upper portion thereof, asshown in Fig. 3,being slightly contracted.

To insert the pole after cutting it to the desired length, Athe operatorbrings it into engagement with the inclined entering lips D, as shown indotted lines in Fig. 3, and then forcing it down into the socket,whenthe arms 5o C will spring overthe upper portion of the pole and lock itagainst accidental disengagement. This construction of device I nd to beexceptionally simple and effective.

The lugs B not only serve as securing means, but prevent the end of thepole from striking the paint and thereby marring it in turning orhandling the pole. They also serve to space the arms C from thewoodwork, so that the motion thereof will not scratch the paint. 6o

Another advantage of my construction is that the arms C springtightly-upon the pole and clasp it firmly to prevent it from turning.This is desirable, because it is found in putting up poles which areslightly bent if the bend is put in upward it does not show so plainlyand the load is tending always to straighten it. These spring-armsenable me to dispense with pins or prongs to hold the pole from turning.

What I claim as my invention is l. Apole-socket formed of a single pieceof sheet metal bent into any upwardly-opening segment of a circle,slightly greater than a half-circle and securing-lugs struck up from 75one edge intermediate its ends.

2. A pole-socket formed of a single piece of sheet metal having struckup from one edge intermediate its ends apertured securinglugs, and bentinto a segment of a circle 8o slightly greater than a half, and inclinedentering lips at the top.

3. A pole-socket formed of a single piece of sheet metal comprising thebody portion A bent into a segment of a circle slightly greater 8 5 thanthe half, the two central apertured securing-lugsB bent at right anglesto the body portion and projecting substantially the thickness of themetal beyond the rear edge thereof, the parts being arranged as and for9o the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
